L-Normalizer
Loudness Normalizer and True Peak Limiter VST, AU, AAX plugin and standalone application
L-Normalizer
 
The next logical step after releasing the loudness meter application, ALM 5.1, was to create an affordable, cross-platform loudness normalizing tool: the L-Normalizer. This particular application can be very useful and helpful for audio engineers working in post production and broadcasting environments. The major two steps of the workflow consists in analyzing the audio material and rendering an improved one. If you choose to normalize your material, you can pick between program loudness or short term loudness, if your materials are shorter than 30 seconds. Also, a True Peak Limiter is available with variable knee width, release time and true peak. In order to analyze and normalize the audio file of your video, we’ve created the L-Normalizer Standalone version.

Features
  • Loudness Normalizer and True Peak Limiter – VST, AU and AAX plugins.
  • Fully compliant with international loudness standards : BS-1770 (rev.3), EBU R128, ATSC A/85 and ARIB TR-B32 specifications.
  • Analyzing and Rendering capabilities.
  • Channels Format : mono, stereo and 5.1 with automatic detection of track numbers.
  • Correction for either Program Loudness or Maximum Short Term Loudness.
  • Adjustable settings for True Peak Limiter: maximum true peak, release time and knee.
  • It can be used as an offline plugin but also offers real time processing, if the plugin is inserted on a track.

Descriptors
  • Integrated Loudness or Program Loudness (in LUFS or LU) – describes the long-term integrated loudness of an audio material from ‘start’ to ‘stop’.
  • Max Momentary Loudness (in LUFS) – the maximum value of the Momentary Loudness of the entire program calculated with a time window of 400ms.
  • Max Short Term Loudness (in LUFS or LU) – the maximum value of the Short Term Loudness of the entire program calculated with a time window of 3s.
  • Loudness Range (in LU) – loudness dynamic range from ‘start’ to ‘stop’ that helps you decide if dynamic compression is necessary.
  • Max True Peak Level (in dBTP) – indicates the maximum value of the signal waveform in the continuous time domain (this value is calculated using inter-sample peaks that can be missed in quantization).
  • Release Time (in sec) – the time it takes to turn up the level again after the signal peaked.
  • Knee Width (in dBTP) – controls whether the bend in the limiter characteristic has a sharp angle or has a rounded edge. The Knee Width is the threshold-determined point where the limiter becomes on/ starts working.

Standalone version
The Sound Field can use one of the two types of loudness, to create a real time view of the surround image of the signal:
  • Momentary Loudness
  • Short Term Loudness
The axes are the same as for the Loudness Meter Indicator or for True Peak Meter, depending on your choice. For True Peak Loudness, the representation of LFE channel will be included. The Max. Short Term Loudness threshold will also be used, the bar becomes red if the value is above the limit.
